I build some vehicles and width seems to influence top speed the most. I drive vehicles as big as the RV or smalller. On roads at day light I do 140/160 kmh. When I do know the road I hit max save speed often. 200/250 Kmh is still driveble mostly due the good breaks you have when using the handbrake. Accelaration is what you stop from driving at mach 1 in the current game

Heres one of my special vehicles i build a while ago.

No solar cells installed nor needed.

Here is a light vehicle that I originally built in version 7128 (the most recent build I used it in is 7847).

I named it the Loot Scooter.

Its purpose was to transport me from home base to an area that I wanted to loot and then transport me and my loot back to base.

It is 3 tiles by 3 tiles (at widest). The layout is this:

123
. 4 (Ignore the period, leading spaces keep being ignored)
567

tiles 1 & 3 = frame, 17" wheel (steerable)
tile 2 = frame, headlight, large electric motor
tile 4 = frame, clock, 5-point harness, controls, seat, swappable storage battery case, storage battery.
tiles 5 & 7 = frame, 17" wheel
tile 6 = frame, solar panel, cargo space

I had a small one-man dune buggy in mind when I designed it. My mental image of it has a roll cage built with pipes around the seat, but I could not build that part in the game.

Stats are:

Safe/Top Speed: 182/320 mph
Acceleration: 17 mph/t
Mass: 1090 lbs

How fast I drive depends on obstacles but when I can I run 80 to 100 mph. I could live with 60 mph if I had too.

[mlangsdorf]

Small vehicles are mostly getting a boost, though you’ve already got a large engine on a small vehicle so you’re getting a downgrade. Still, current estimated cruise speed is 120 mph.

[Rose]

Are gearboxes coming anytime soon? Or ever?

[Theundyingcode]

This thing has appeared in the majority of my games for day-to-day use. I play with a static base and this thing is what I use to collect the parts for the larger deathmobile that i’ll use for longer hauls. The death mobile tends to change based on what I find but this my baby.

[mlangsdorf]

I need wheel count and size and acceptable vehicle speed, please.

[Theundyingcode]

I need wheel count and size and acceptable vehicle speed, please.

7x1 + ram. (occasionally i’ll cut one frame)
x2 wide wheels
Speed is 305/472 km/h unloaded. IIRC it will still do 150+ loaded but I rarely drive more than ~120 km/h or so for fear of crashing.

[DrakeDragon8]

This is probably a bad Idea buuut… I have 1 Enhanced motor, 1 large motor, 1 footcrank, 3 alternators, 6 25 in. wheels, 5wx9l with a 7x7 attached, windshields in front, doors at side and back. Safe is 87 Max 342 I normally drive at 20 but have been known to go upwards of 50 to 80

[mlangsdorf]

I like how you have my standard APC as the front of your vehicle, and then you have another vehicle and ANOTHER vehicle attached to it. Formula nevertheless gives you a 55 mph cruise speed (probably, you may have an atypically bad coefficient of air drag but meh.)

[DrakeDragon8]

I built this from scratch with a plan for drivers seat in a 3x3 to protect from diagonals and a 3x3 of seats behind for sleep and NPCs and a 5x5 for crafting area with MANY cargo areas.

[DrakeDragon8]

Too my absolute HORROR My power went out for all of about 10 seconds but that was all that was needed to corrupt my games destroy my options json and mess with my save so now my character is currently sitting in the middle of the street Deathmobile disappeared and somewhat luckily I had all my items in my inventory so I could fight off the NUMEROUS freshly genned zombies Including hulks but uncanny dodge and flashbang generators helped alot. :'C

[TheZoneWizard]

…uh…are you seriously going to make a “normal” speed of 120mph?

Sooooo…a 3 ton car will chill at this speed normally?

I hope this is a typo. We can go 30-40 normal now in a swat van and this seems totally legit. But come time for your changes and 120 is normal to you??

This is the sorta thing that will instantly break the game if that is seriously intended.

Edit:
For an example-

A very fast train at around 375mph. The average car can’t do 150mph without doing damage to itself. Certainly being able to reach this speed would be possible, but it would also kill the car.

[mlangsdorf]

So a 1 ton car with a 250 HP engine having a cruise speed of 120 mph will totally break the game, but that same car keeping it’s current cruise speed of 180 mph is totally acceptable?

Porsche could get 993 in 1995 to a max speed around 165, with less than twice the power and half again the weight. Power scales with the square of speed and linearly with weight, so the top speed of that bike should be roughly 85% of the 993’s or about 140. If the max speed is 140, achieving 120 without redlining the engine seems fairly plausible: you’re only get 33% more power at 8000 RPM than you are at 6000 RPM (roughly), so your max safe speed should be about 85% of your absolute maximum speed.

But hey, I’m just a guy who knows a little about physics and a little about programming. I linked to the GitHub issue at the start, and I’ve laid out all my math and logic there. Cake-pie has already corrected me on some of my math and physics, and we’re working to make the algorithm better. So if you know more, I welcome your contributions.

If your objection is that I’m going to make the numbers less unrealistic than the highly unrealistic numbers we have now while not making them completely realistic, well, thanks for the information.

[Rose]

Point is, the gearboxes are limited.
As @TheZoneWizard said,

but it would also kill the car.

From my own life expirence, I’ve tried flooring it in my own car, and I could only reach about 110 mph, before the engine redlined, the gearbox overheated and started freaking out.

So yes, reaching speeds above 100 mph in an average vehicle is sort of doable, but probably isn’t a good idea if you’re intending to keep using the car.

I’m not talking about porshes or such. Those are built for acceleration and speed. But average cars just can’t perform as well.

Even a humvee, which i’m driving now ingame, can easily reach 100 mph in cdda. In real life it’s centered more on offroading, thus the presence of individual torque converters for each wheel and a massive engine with a high fuel consumption, and it’s sort of harder for a real humvee to reach high speeds than to climb hills, traverse fords, and so on.

And I know this is not doable until we have gearboxes, which we discussed earlier, but man… top speed of 1000+ km/h for a police car with a V12… and a safe speed higher than that of an airliner… that’s really worth fixing, even in a not-completely-realistic kind of way.

[mlangsdorf]

Current proposal puts the safe speed of a car at 85 mph, max at 105. The FBI car with a v8 engine will have a safe speed around 100 and a max around 120 mph.

Those look like reasonable numbers to me and seem to match many other people’s expectations.

Again, if you want to comment on the design, please contribute via GitHub.

[Rose]

Have you also thought about fuel consumption?

please contribute via GitHub.

Well, sorry, i’m not a programmer.

[mlangsdorf]

I’m not asking people to help with the programming. I’m still reviewing the design, and that discussion is mostly about physics and expectations and is happening via comments on GitHub.

I haven’t thought much about fuel consumption. It will need to be adjusted to match the current fuel consumption tests. There may be further adjustments in the future but that’s beyond the scope of this discussion.

[Vastin]

Yeah, the basic speeds your talking about for standard cars sound fine. Our heavily loaded uber-mobiles are presumably going to go a fair bit slower, given that they are generally built to be the equivalent of an APC/hauler. (at least until such time as someone actually decides to model the kind of ultra-powerful turbine engines that modern tanks employ, with their absurdly bad mpg…)

Where things will get really ugly for vehicles trying to go very fast would presumably be fuel consumption. A cop car with a V8 easily can go over 100mph, but its mpg suffers badly due to the constant fight against drag, friction, and presumably some loss of engine efficiency from high heat levels.

Right now I don’t know if the game models loss of fuel efficiency for higher speeds at all. I assume it does, but have never really tested it. ???

[mlangsdorf]

Vehicles consume fuel every time they accelerate, in proportion to the instant acceleration to maximum acceleration and relative to engine power. Currently, vehicles slowdown some amount each turn and then accelerate back to their cruise control set speed.

The proposed changes will make vehicles slowdown more at higher speeds, but the consumption formula will be adjusted so that vehicle range doesn’t change much.

[TheZoneWizard]

So just one more comment concerning speed and weight and all that.

I understand a cop car with a good engine can peak at a 120mph. But my 2 cents(assuming this wasn’t already added). There should be some wear and tear that increases with more strain on the engine.

Vehicles should be taking a scaled damage to the components. Damage around the wheels from high weight and torque(I made a booboo of my first motorized bicycle irl…too much torque destroyed the wheel). Too much torque even without high weight “petal to the metal” 0-60 kinda stuff.

Engines having a “peak” rating. In which the comfort zone yellow lines and anything over that scales + weight = damage to the engine. Going into the Red line.

Engines are strange and although I am an amateur in the mechanic realm. My experiences with electric and gas powered bicycles has taught me quite a fair amount from nothing.

Caveat- Wanna laugh yourself silly? Invest a few minutes into videos and design specs of a Yugo car lol
OMG that cracks me up. Its like CatDDA but in real life! bahahahaha! xD

edit:

Are tank being changed or did I find a really strange tank? What happened in my latest game today as follows;

I ran around scavenging as usual. Night came and I was getting tired. I found a tank in decent condition and as I have many a time, snuggled into the control seat for a nap. I ended up being eaten while I slept and died.

So…ok, I thought that sucked…but wait. Closed every door in the tank before I slept and the armor is pretty solid. I was munched by a normal zombie…did…did that little sob just literally chew its way through a friggin TANK??? wtf??? 0_o

So, I’m not angry. But I just remembered this and I am still wondering wth happened to the tank armor that a zombie can claw and chew through…ya know…a tank? A plastic shell on a car or truck. Seems legit. A tank…? Nope. Thats malarky I don’t care why. Any effort at all to change this would be appreciated. I know I seem to bring rants. But this isn’t a rant. Just shedding light on this odd thing that happened and hope it can be corrected. Thanks! =)
